[TRNSYS-users] Pergola as Shading mask

Murielle,
   You are correct that when calculating the 
shaded radiation falling on a facade, Type34 
assumes that the overhang and wing walls are 
opaque. However, Type34 also outputs the fraction 
of the facade that is shaded and the fraction 
that is unshaded. If you were able to define a 
translucence for the pergola (in other words the 
pergola doesn't fully block the sun but only some 
part of it. The translucence would be a measure 
of the fraction of sunlight that is allowed 
through either when vegetated or unvegetated.) 
then I think you could use the Type34 shading 
fractions, adjusted for a translucent overhang.
Kind regards,
  David
